Occurrence in Nature - Lead

The main type of lead that is found in galena, PbS, which is about 87% lead. Two other common minerals are cerussite, PbCO3, and anglesite, PbSO4. These two occurs commonly near the surface. Lead, when it is a hot fluid, may be trapped in cracks and creates veins. If it is in limestone, it fill cavities to form patchy deposits.

CERUSSITE BROKEN HILL - RocknCrystals.au

PbCO3: Lead Carbonate. Cerussite is a popular collection mineral. It is famous for its great sparkle, great density and amazing twinned crystals. Cerussite is a minor ore of lead. It has a very high luster due mostly to the lead content. Just as leaded crystal glass sparkles more brilliantly because of its lead content, so too does Cerussite.

how lead is been extracted from its ore? | Yahoo Answers

Jul 03, 2008 · The principal ores of lead are galena (PbS), anglesite (PbSO4) and cerussite (PbCO3). Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more.

Lead Carbonate | AMERICAN ELEMENTS

Lead is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead containing minerals. Lead does occur as a free element in nature, but it is rare. It is a dense, soft metal that is very resistant to corrosion and poorly conductive compared to other metals.
